PAPER KEG.

To all whom it may concern Be it known that I, BERT C. VAUGHN, a v

citizen of the United States, and a resident of the city of Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Paper Kegs, of which the following is a specification.

This invention relates broadly to paper receptacles and more especially to a paper keg.

The principal object of this invention is to provide a reinforced keg formed substantially entirely of paper.

A further object of this invention is to provide a keg formed substantially entirely of paper stock and comprising a body portion of a paper tube reinforced upon its exterior with hoops made from sections of a paper tube; both the body portion and the hoops being cemented together with silicate of soda.

Other and further objects of the present invention will. in part be obvious and will in part be pointed out hereinafter by refer ence to the accompanying drawings wherein like characters are used to represent like parts throughout the several figures thereof.

Figure 1 is a perspective view formed in accordance with my invention. Fig. 2 is a. longitudinal sectional elevation showing a sectional view of my invention. Fig. 3 is a detail view showing a transverse section illustrating the action of the supporting hoops.

Prior to my invention kegs have been formed of various materials including thin layers of wood usually referred to as veneer. These layers of wood ordinarily are superimposed and secured together usually by nails. Also in this construction wooden hoops have been used as supporting members. Paper kegs have also been formed with smooth exterior walls or with hoops that were formed directly upon the exterior wall.

The present invention resides more especially in the formation of a very cheap, at the same time efficient paper keg of relatively great strength. The difliculty encountered with large size paper containers such as kegs is the liability of such container to crush due to exterior forces that may be thrown against the side wall of the container at its weakest portion intermediate the heads. After a series of practical Specification of Letters Patent. Patented 1 12, 1915 Application filed August 4, 1915.

Serial No. 43,613.

experiments I have found that this difiiculty may be cured by stapling suitable built up paper hoops upon the exterior of the body in such manner that any force directed against the body wall of the container will be delivered to the hoops in such manner that the said hoops act as supporting arches or trusses. By anchoring the hoops at intervals I am enabled to secure a flexibility which permits the forces to be more widely distributed than where hoops are formed integral with, or are cemented to the side wall of the container, and consequently actual practical use of the container herein disclosed demonstrates its ability to withstand rough usage better than the previously specified types of devices.

Referring now to the drawings, the body portion of the keg is formed from a section of a continuous paper tube which is built up of superimposed layers of paper boardthat are cemented together with sodium silicate. While various types and sizes of tubes may be used, the tube which is used in practice in this keg is substantially ten and one-half inches in diameter with the side wall 1 of substantially one-fourth of an inch in thickness. In the present invention preferably a pair of inside hoops 2 are formed from a short section of the same tube as the body portionwith a small part of the tube cut away and the section compressed upon itself to secure the necessary smaller diameter to use this hoop inside of the main body portion 1. The heads 4 of the present container are made of flat paper boards which likewise are formed of tion and cementing the various layers of paper board together with sodium silicate. To secure these heads in position outer end hoops 5 are provided, which aresubstantially the same as the inside end hoops 2. ixterior end hoops 6, usually referred to as chime hoops, are provided adjacent the ends of the body portion 1 and are constructed so that the end of the body portion 1, the outer hoops 5, and the chime hoops 6 all terminate adjacent each other in such manner as to provide a strong thick chime to withstand destructive forces that come against this portion of a container when it is in transit or being shipped.

Intermediate hoops 7 are provided on the exterior of the body portion of the keg in- -termediate the ends thereof and it is with reference to these hoops particularly that the present invention relates. The various hoops disclosed in the present invention are secured in position by means of metal staples 8 that are formed from thin strips of metal which are suificiently strong and'malleable to sustain considerable force, at the same time bend with sufiicient ease to enable these members to be clenched in position.

Referring now more particularly to Fig. 3, it will be noted that the forces A. coming against the body portion intermediate one of'said hoops will cause the hoop to expand very slightly from the body portion and bulge outwardly very slightly. lhis slight bulging is indicated in an exaggerated ef feet by the dotted lines as at B-B interniediate the staples X and YY. This force A is further distributed beyond the staples Y-Y and causes a further bulging as indicated by dotted lines CC. This however is further removed from the force A and consequently is of a less degree than is the bulge'at BB. llt will be noted that all of the staples shown in Fig. 3 are under ten sion, with the exception of the staples ZZ, therefore it will be noted that any force against the exterior of the keg which tends to crush the keg wall has a tendency to set up counter forces in the hoops 7, which counter forces pull outwardly on the said side wall and thereby greatly assist in re sisting crushing forces brought against the side wall of the tube.

From the foregoing description it will be noted that the present container is formed substantially. entirely from paper with a minimum amount of metal. The only metal being used to hold the parts together are the staples 8 referred to. I p

Having thus describedvmyinyention What I ll desire to claim is 1. A paper keg having abody portion comprising a paper'tube formed of a. plurality of layers of spirally Wound superimposed webs of paper cemented together with -silica-te of soda, paper heads within saidbody portion, said paper heads comprising paper boards built up of superimposed. sheets of papercemented together under. pressure by silicate of soda, inside head paper hoops also within said body portion and abutting said heads on each side thereof to hold said heads in position, chime hoops comprising superimposed layers of paper cemented together with silicate of soda, said awassa chime hoops having their outer edges substantially coincident with the outer ends of said body portion and being of a width Suficient to lap said inside hoops to progide a thereof, said intermediate supporting hoops comprising sections of a paper tube formed of-superimposed paper webs cemented together with silicate of soda, and staples spaced at intervals around said intermediate hoops to anchor said hoops and said body portion at predetermined intervals in such manner that forces tending to crush. said body portion adjacent said intermediate hoops are transmitted through said staples as tension members and to said intermediate hoops as a compression member to sustain said body portion under such forces.

2. As an article of manufacture, a paper keg having a body portion comprising a section of a cylinder Whose wall is composed of superimposed layers of paper cemented together by silicate of soda, heads secured within the ends of said body portion, and a supporting hoop intermediate the ends of said body portion-and constructed to sustain the part of said body portion intermediate the heads, staples penetrating said supportinghoop and said body portion, said staples being spaced apart at predetermined intervals to separate and localize the attachment of said hoop to said body portion in n such manner that forces tending to crush said body portion are transmitted through said staples to said hoop to render said hoop a compression member tending to resist such forces. 1 I
